APPARATUS FGR CASTING TYPE-BARS.

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filed January 14, 1919. Serial No. 271,014.

. residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Apparatus for Casting Type-Bars, of which the following is a specification.

This invention relates to new and useful improvements in apparatus for casting type bars, and pertains more particularly to the matrices employed in the above operation.

Heretof-ore the type bars as formed were not sufficiently low to prevent contact of the blank portion of the slug with the paper printed, thus causing at the ends of the lines, black and unsightly blots of ink which are particularly objectionable where large head lines are used as in newspaper work.

It is the primary object of the present in vention to provide a matrix for use in connection with all types of type bar casting machines by which the above objectionable feature is entirely eliminated.

Referring to the drawings Figure 1 is a sectional view of a port-ion of the mold box of a linotype machine and showing in section a matrix constructed in accordance with the present invention.

Fig. 2 is a similar view showing the operating parts of the matrix in the initial step of operation.

Fig. 3 is a similar view showing the position of the parts after the operation has been completed.

Fig. & is an edge view of the matrix, and

Fig. 5 is a detail View of one of the operating members in a modified form.

Referring more particularly to the drawings, the reference character 10 designates the mold box ordinarily employed in type bar casting machines, and 11 designates the slug forming chamber thereof.

The front wall of the mold box 10 is out out as at 12 and 13 to form a projecting lug or the like member 14: which lies below the slug forming chamber 11.

The matrix is designated by the reference character 1, and is provided with two passages 15 and 16, the passage 16 being reduced as at 17. The rear edge of the matrix is out out as at 18, said out out portion extending throughout only a portion of the length of the matrix.

Mounted in the passage 16 is a plunger 4 which is provided with a squared head 19,

operation is as adapted to be received within the enlarged portion ofthe passage 16 as shown.

Mounted for sliding movement in the passage 15 is a slotted lever 20, this lever 20 being retained in the passage 15 by means" of a pin 7 projecting through the slot 22 in said lever. The bottom edge 21 of this slotted lever is angular as shown in the drawings which provides a slight space 21 between the bottom edge of the said lever and the bottom wall of the passage 15. By this construction, it will be seen that the slotted lever 20 is capable of a pivotal movement about the pin 7 for the purpose of permitting the reduced end of the slotted'lever 2O to move into engagement with the bottom wall of the passage 15 where it will be positioned behind the lugsof the matrix to prevent interference of the slotted lever 20 with the distributing mechanism of the machine.

Extending transversely through the ma trix 1, near the rear edge thereof, and also projecting through the out out portion 18, is a pin 6, and mounted behind said pin 6, is a flat resilient member 3, the said resilient member 3 being bent around the pin 6 as shown at 23.

The lower end of this resilient member 3 is adapted to engage with the inner end of the slotted lever 20, the upper end of said resilient member 3 engaging in a cut out portion 2% in the inner end of the plunger 1.

The matrix is also out out as at 25, and mounted in said out out portion 25 is a coil spring 26, the free end of which engages with the inner face of the resilient member 3.

Having thus described the invention, the

follows:

When the matrices have been properly positioned the mold box is moved toward the first elevator to properly position the type casting portions thereof opposite the slug forming chamber 11 thereof. With this operation, the slotted lever 20 engages the projection 14 of the mold box 10 and moves the said lever 20longitudinally of the recess 15. This movement of the lever 20 rocks the resilient member 3 about its pivot 6, and owing to engagement of its upper end with the plunger 4, the head 19 of said plunger 4 is forced into the slug forming chamber 11 of the mold box 10 as shown in Fig. 3. With the parts in this position, the spring 26 is placed undercompresslon, and said spring serves to return the several parts to their normal position shown in Fig. 1 when the mold box 10 is moved away from the lines of matrices.

Referring to Fig. 5,'it will be seen that the plunger it may be formed in two separate members and 31 the member 30 being cut away as at 32 and provided with a shoulder 33 with which the shoulder 34: of the member 31 is adapted to engage to limit longitudinal movement of the members 30 and 31 with relation to each other. Mounted in the cut out portion 32 is a coil which serves to keep the member 31 moved forwardly at all times.

These two members 30 and 31 are provided with head sections 35 and 36 respectively andthe sliding contact of the head sections is on an angular line as shown at 37.

By this construction, it will be apparent that should the plunger member fail to exactly register with the slug forming chamber 11 of the mold box 10, movement or the members 30 and 31 will permit oi the head sections 35 and 36 moving to completely close the slug forming chamber openmg.

From the foregoing, it will be seen that the present invention provides means by which the slug surface which is not formed spring 3 l is claimed is 1. A matrix having a plunger mounted for rectilinear movement therein, a sliding member carried thereby and meanslconnecting said sliding member and said plunger to actuate said plunger upon movement of the sliding member.

2. A matrix having a yielding plunger mounted for rectilinear movement therein, a member carried thereby having an oscillatory slidin movement and means operable upon movement of said member to actuate said plunger.

3. A matrix having a plunger mounted for rectilinear movement therein, a sliding member, and pivoted resilient means connecting said sliding member and said plunger for moving said plunger upon movement of the sliding member.

In testimony whereof I have aifixed my signature.
